This paper is reporting the data of a preliminary study on heavy metals distribution in fluid and solid phases involved dry classified aluminium hydroxide production through Bayer process. For released phases, main source contamination bauxite its mineralogical soluble or insoluble alkaline solution. It was shown that predominant way to transfer contaminating elements particles occlusion very f...
Underground bauxite mining exploitation is a challenging environment for ventilation. In this paper, such complex underground ventilation network modeled in detail using the Ventsim software. The and its characteristics are selected developed through software, followed by their calibration validation against actual measurements of both airflow quantity quality which have been carried out at min...
Spherical particles based on bauxite-type raw materials, commonly referred to as proppants, are state-of-the-art for particle receivers of concentrated solar power plants. Particles heated in a fluidized reactor by focused sunlight and transported heat-exchanger or storage tank. Therefore, key properties absorber high absorptance mechanical endurance. Due their relatively poor content color-giv...
Low-cost magnesium aluminate spinel ceramics were successfully synthesized from the minerals of magnesite(M) and bauxite(B) via one-step sintering method. The effect ratio bauxite to magnesite on phase evolution, microstructure, as well mechanical properties was thoroughly investigated. structural analysis indicated that Mg2+ or Al3+ ions dissolved in lattice formed Mg-rich/Al-rich MgAl2O4 (MA)...
In the present study, prediction of Alumina recovery efficiency (A.R.E), the amount of produced red mud (A.P.R), red mud settling rate (R.S.R) and bound-soda losses (B.S.L) in Bayer process red mud has been carried out for the first time in the field. These predictions are based on Lime to bauxite ratio and chemical analyses of bauxite and lime as Bayer process feed materials. Radial basis func...
We recently developed two databases and a laboratory information system as resources for the metabolomics community. These tools are freely available and are intended to ease data analysis in both MS and NMR based metabolomics studies. The first database is a metabolomics extension to the BioMagResBank (BMRB, http://www.bmrb.wisc.edu), which currently contains experimental spectral data on over...
Western Australia is unique in its botanical diversity. There are over 7000 species of native vascular plants of which over 3000 are endemic (Keighery 1992). Phytophthora cinnamomi has a major impact on this diverse flora and directly effects over 2000 species from a diverse range of plant families (Wills 1993). Its indirect effects in terms of botanical impact through the loss of vertebrate an...
